West Ham United co-owner David Sullivan cannot guarantee the future of manager Gianfranco Zola.

The Times says Sullivan was unwilling to make any comment about the manager's future when asked about his position on BBC Radio 5 Live yesterday.

Senior officials at the club asked Zola whether he felt he was still the right man for the job in the wake of the 3-1 defeat at home to Wolverhampton Wanderers on Tuesday. Zola responded positively, insisting that he wanted to remain for the duration of the survival fight this season. Should the Italian be dismissed he would be entitled to significant compensation with three years remaining on his contract.
